Girls can sing in tune at an earlier age. Early linguistic bias often prevails throughout life. Girls read sooner, learn foreign languages easier, and as a result, are more likely to enter occupations involving language mastery.

Research evidence finds that girls differ in their approaches to gaining knowledge about the world. They tend to favor a "communicative mode": asking others, taking advantage of other people's experiences, sparing themselves the need to personally encounter all the objects in their environment. Thus, girls tend to conform by relying more on social cues. Since they are better equipped in the auditory mode, they can pick up significant information from tones of voice and intensity of expression (women's intuition?).

Boys show an early superiority in visual acuity, which compensates to some extent for their lowered auditory capacities. Boys are generally clumsier, performing poorly in fine motor performance, but doing better in gross total body movements, particularly those requiring fast reaction times (football, construction?).

Boys are more curious, especially in regard to exploring their environment, and are better at manipulating three-dimensional space.

Boys use their right hemisphere consistently for spatial processes; their left for cognitive processes. Girls tend to use both right and left hemispheres to solve a spatial problem, which can sometimes result in an interference phenomenon- a kind of log jamming in which the use of words to solve a spatial problem results in slowed, incorrect, or even absent responses.
